' PLYMOUTH, OHIO, AVlOORPORATION OF OHIO.

To all 'whom 't may concern Be it known that I, FLOYD B. CARTER, acitizen of the United States, and a resident of Plymouth, in the countyof lRichland be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the characters of reference marked thereon, which form a part ofthis specification. f

My invention relates to ware forming machines and it particularlyrelates to clay cutting machines. c

My invention is particularly applicable to ware, formed by processeswherein the molded clay is linearly ejected from a forming die. Themolded clay is then manipu lated and cut up into parts as desired.

The invention particularly has to do with the cutting of the clay alonga definite line without mutilation and withdrawing the cutter withoutinjury to the ware, as well as with the manipulation of the claypreparatoryto the cutting process.

In the constructions embodying my invention, the ware, such as tiles,bricks, and other clay products, preparatory to baking are cut by meansofa stretched fine wire or similar cutter, while the formed clay isbeing conveyed through the cutting machine.

The invention may be contained in many constructions all of which comewithin the purview of my claims hereinafter appended. To show thepracticability ofconstructions embodying my invention, I havel selectedone of such constructions as an example and shall describe ithereinafter. The construction selected is illustrated in the'Vaccompanying drawings. .y

the cutting arms or the denting arms may be removed from theirsupporting pins. Fig. 6 illustrates a side view of a part of themechanism, showing a buer for yieldingly holding the cutters. Fig. 7 isa transverse sectional view of part of the mechanism shown in Fig. 6.

Referring to the figures, of the supporting frame. 2 are guide tracksfor guiding the linked members 3 having the rollers 4. movable over thertracks 2. The linked members 3 are provided with supporting boards orconveyer plates 5. Y The plates 5 may be varied according to the shapeof the moldedfclay, as, when bricks are formed the plates may presentfla-tupper surfaces,lor vif tiles are ejected from the molding die, thesurface `of the conveyer plates 5 may be cylindrical. The link parts areeach provided with endl frames 6. The adjoining end frames 6 are kept inspaced relation. They are provided with cross pieces 7 located on theupper ends of the end frames 6 and forma spacing element between the endframes. The cross pieces abut and then form Va solid continuous framefrom near one end of the machine .toV the other. The outer edges of theend 1 is a portion frames are maintained in a vertical position as theyare moved along a greater part of tracks.y The upper ends of the framesare rounded so as to, receive and guide therollers l0 mounted on theindentation arms 11 by means of the pins 12 Vwhich are keyed to the armsby means of the screws 18. rThe arms 11 are mounted ontheindentationreel or disk 14;, and are pivotally connected to the plate 14by means Ofpns 15 keyed to the plate 14 by means of the screw bolts 16.The arms. 1l extend through slots 17, which are large enough to permit a`certain amount of free movement of the arms 11 with respect to theplate 14. The indentation armismade T-shaped and the outeredge isprovided `with a ridge 18 having, ysnuous sides 19 propelled position, 2

the same as the length ot the brick sothat as the molded form passesbeneath the reel, the upper surfaceI is pressed inwardlyby the edges 18as the molded 'ormpasses along: Vhen bricks are to be formed, theV`alternate adjoining edges oic the plates 5 are provided'` with upturnedportions which press into the molded ormS while it is received -from thedie. The upturned portions am-'located centrally with respect to thespaces, between the falternate end trames'fso' that`tl'ieindentationsfforined by the'arms lliare lo,`4 catedopposite theindentations formed by the raised portions 20.

The Vslots' or notches'17 in which thearms 11 are located are made of awidth suiicient to allow :for any change of relationbetween the*horizontally moving links 3 and end frames 6` and the rotary movement ofthe reel14; The'arms'll, as they are rotated, drop against one l end'of: their associated notches 17 as they pass the vertical center linethrough the axis of the reel. In this they ar-e carried down and enterinV betweenthe-frames 6 and the reel 14 is then propelled `bycontactofthe'edges or" theranies` Gwith thei rollers 10.

Thearms extend through slots or notches 43 and have tree 'movementsabout the pin 41 but within theflimitations of the slots 43. Thearmslare provided with steel catch pins 44e: which penetrate-recesses45. `The steel pins are springfpressed by means ofthe` `springs46 whichare co-mpresse'dfby means otfthe` tap bolt 47.

pvotpin `41 is provided with a rounded or tapered nose, while the pin 44is provided witha shoulder to"v prevent the` spring46 from pushing thepini 44 out of the counterbored. recess. Frequently while machines ofthe type shown in the drawings are running,

the Wires break and ordinarily it is necessary to stop the machine inorder 'to replace the'broken wire; lhen the wire 30 breaks all that isnecessary is to pull the cutter arm oil while the machine continues itsoperation and put another cutter' arm in its place. This saves loss of agreat kdeal ottime in the operation of the machine. rlhe inner end otthearm 31 isbi'tuicated and* a roller 50 is mounted between thefurcations.

Thek reel 40 kis mounted on"the shaft 53 which hasbearings inthestandards 39. Al

cam51 is connected tothe supporting shaft by means of a-bolt 54.`

As' the'links 3,'tcgether-witl`i the molded clay, are carried along, therollers 48 se cured 'tothe pins 34 and 35, enter between the end 'frames6 and are carried 'downward and Avertically 'guided by the edges of theencl-;t`iaiiies As the rollers move downl verticallyvwith respect totheclay the wire `cuts the clay. rlfhe arms`31fwhen'k the rollers aremoving vertically downward with respect to the horizontally moving'clay, propel the wheel and bringthe arms in succession downward andIinto cuttingrclae" tion 'withltlie moldedcl'ay.' The wires ot theadjoining arms are'spaced apart so that they will cut alongtheindentations formedby the ridges 18 on the arms' 11 and bytheupturned portions 2010i1 the plates 5. PinsV 49 located nearthefollowing side oth'e arms 31, make contact with the leading side of theend frames '6 lasthe cutters 30 are withdrawn from/the plate vand so asto' ad'- vance thecutter with respect to theclay as it'rises from thebottom'edge andpasses the upper edge thereof. The cam'fl, however, is sopositioned on the shaft 53, such that the rollers 50 press i against thecam 51 rand tilt lthe-lower ends of the 'arms 3lfor`wa'rdso`f`-thatfitwill'i follow the" endfsurtac'e of each preceding' article'as the links 3 pass?I theincli'ned portion of the track'2. The'` armswhich at 'thispoint'arerisinglupward l while' the movement oftheendit'rames 6 which are at this point moving substantially horizontallywith a slight declination. l The pins"49*also'foperate 'to' produce' theclearance-it1 thecain 51 becomes displaced or does not perform' thisclearing action correctly.

The` slotsl ornotchesf43 are longenough to* allow the lrequired changein' relativemovement betweentherotated arms and the links` 3./ When the'rollers 48.first'pass between the end frames thewheel 40,'together witlrthe arms, arepropelled by the end frames time,l press against theadvanced ends of the slots 43. As the frames are carried along duringthe process of cutting ofthe clay, they lag with respect to theymovement of the wheel so that when the cutting portion, performed byeach arm, is complete, the arm is located in an intermediate positionwith respect to the ends of the slots 43. When the cutter 48 is to bewithdrawn from the clay andadvanced so that it will not engagek with theclay and to prevent mutilation of the clay, the rollers 50 on the arms31 move against the cam 5l which lifts the outer end of the arm so as toclear the following piece of ware but not so as to strike the advancepiece of ware which at this point is passing down the declined portionof the track. When the cutter is clear ofthe clay, the cam 5l operateson the rollers 50 to raise the arms 3l against the leading ends oftheslots or notches 43. against the advanced or leading ends of the slotsor notches 43 bythe cam 5l until the arms pass the vertical line throughthe axis of rotation whereupon they'will be held upon the leading endsof the slots or notches by gravity, and until they have completed thecutting operation of the clay each time they are brought in contacttherewith for that purpose. c

rlhe cam 5l may be adjusted onthe supporting shaft 53 and the boltslocated in the collar 52-to which itis connected. Withn in the collar 52is provided a brake 57 having preferably a leather face or strap 58which is pressed against the hub 59 of the wheel 40 by means of the bolt60 located in the collar 52. Any other suitable material may besubstituted for the leather face or strap 58. This operates to retardthemovement of the wheel 40 which is actuated by the pressure of the endframes 6 against the rollers 48 on the ends of the arms 3l. Thisprevents the 'wheel 40, together with the arms 3l, from getting out ofstep with the end frames 6 and prevents any jarring while the cuttersare in the clay and prevents any 4engagement between the upper ends ofthe side frames and the rollers 48. i

The wheel 40 runs with a varying velocity and the brake is to controlthe varying velocities of the wheel and keep the rollers i8 in contactwith the end frames 6.

In order to prevent the eect of jarring while cutters are passingdownward through the clay, I have provided'a means for keeping therollers 48 in contact with the following end frame as the rollers passdown between adjoining end frames and to prevent any arring orchattering of the roller with respect to the end frame. By this means,the roller is pressed constantly against the leading edge of thefollowing end frame, and a straight unmutilated cut is produced insteadof a wavy or mutilated cut. The pins 34 and 35 are extended The arms areheldY 62 preferably curved'upward so as to pro-- duce a substantiallyuniform resistance to the pins 60 as'they strike along the arms 62. Thelevers 6l are pivoted in brackets 63 which may be secured `to vthe framel by means of a screw bolt 64, .at any suitable point alongthe frame inorder to secure the most eiicient operation of the buffer lever 6l whenused in connection with the rotating arms 3l. The other end of the lever61 is provided with a weight 65 which is cushioned by means of therubber ring 66 located on a pin 67 secured on the bracket 63 when'theweight drops downward as the lever 62 liberates the pin 60 located onthe arm 3l.

The buffer lever 6l engages the pins 60 of the arms 3l in succession sothat as the arms are guided downward between the end frames 6 and thelinks 8 are propelling the wheel 40, the rollers 48 are pressed againstthe leading sides of the end frames-6 preventing any effect of jarringto which the machine may be subject and also preventing mutilation ofthe cut.

The wheel 40, together with the hub 59 is rotatably mounted on the shaft53 and is held between the collar 52 and the ring 56 which is keyed tothe shaft 53.V The shaft 53 has bearings in the standards 68. Y
